Here’s some of the newer stuff I did with Corona. Average render times were a bit less than 1 hour at 3000px wide on 4 dual xeon machines. Could probably be faster but I just left it at 300 passes and went home.
The cat is an internal joke with the client. Disregard plz.
The lighting is really straightforward - there’s a coronaLight beneath every lamp in the scene. No sun, no HDRI, no"fake" lights. Brute force lighting, if you will.
